Description
The PreSonus Air XD Sub 18 is a high-performance active subwoofer designed for professional use, delivering massive low-end extension and high SPL for large-scale events and installations. Its custom 18-inch low-frequency driver with enlarged voice coil provides efficient power handling and deep, punchy bass with minimal distortion, while advanced tuning options—including variable lowpass filtering, alignment delay, and cardioid/end-fire array presets—ensure precise control of low-frequency performance in any environment.
Powered by 2,000W of efficient Class D amplification, the Air XD Sub 18 delivers clean, consistent output with exceptional headroom for demanding live sound applications. A full-color 2.6” LCD provides intuitive metering, system control, and fast access to DSP presets, EQ, and tuning modes.
Built-in Bluetooth with TWS Bridge Mode enables wireless stereo pairing with Air XD full-range speakers, while flexible routing and direct outputs allow seamless integration into FOH or monitoring setups. Rugged wood enclosures with ergonomic handles, ground-stacking provisions, and built-in caster mounting make the Air XD Sub 18 as portable as it is powerful, whether stacked, flown, or installed permanently.
